    Interesting, well I'm doing an oil change and pulling some gauge wires today so I will take a closer look and let you know what I find.

    Actually the car has a pre-catalytic converter, a front catalytic converter and a rear catalytic converter. All are located upstream of the resonator. Source - Subaru Factory Service Manual/Mechanism and Function Manual. Illustration # 08260781

  6. Stock air box question

    General Maintenance, Troubleshooting & Accidents.
    https://www.youtube.com/watch?v=GS69owXpGdY Engineering Explained did a video on this with a Subaru as a test vehicle no less. There were definitive, measurable gains with the K&N compared to the stock air filter.
  7. Looking for clarification on Koni Struts/Eibach Springs

    Suspension & Wheels
    Yeah I think coilovers would beat me up too much driving to work everyday. I think I will do the Koni's on stock springs first, then try the RCE Black Springs. I want to only change one variable at a time so it is easier to understand the changes felt in the car. The only thing I am waiting...
  8. Looking for clarification on Koni Struts/Eibach Springs

    Suspension & Wheels
    From what I hear the KWs are height adjustable only. I am more interested in damping adjustability than height adjustability but thanks for the recommendation! If I ever pony up the dough for coilovers I'm going to go full retard and convert my suspension/wheels to STI spec then get the Ohlins...
  9. Tesla Model 3--who wants one?

    Comparison: WRX vs World
    I assume you mean a 'cradle-to-grave- analysis. A quick google search gave me this: https://www.technologyreview.com/s/517146/are-electric-vehicles-better-for-the-environment-than-gas-powered-ones/ The short of it is that Renault did an analysis comparing a model of theirs that is electric to...
  10. 2012 hatch dash vibrations

    Interior Mods
    I have a '13 Hatch and just recently went through the entire dash and rear trim to eliminate various rattles. I used some rubber-foam strip I found at Home Depot and applied it (usually one or both sides has adhesive) to the back sides of each trim piece where the piece butts up against the...
  11. Built Motor, Stock Tune, Longer Life?

    Engine Modifications
    Yeah I guess Hennessy was a bad example, I had heard the guy was a real **** but didn't know about him scamming people. Well I think my original question has been answered, modifying the engine's internals decreases overall reliability regardless of quality of aftermarket parts. I'm glad you...
  12. Built Motor, Stock Tune, Longer Life?

    Engine Modifications
    ...what? lol. Over 75% of the American workforce drives to work everyday...
  13. Built Motor, Stock Tune, Longer Life?

    Engine Modifications
    Great info, and thanks for adding some personal experience to the discussion. I guess I underestimated the precision the OEMs are capable of. I had wrongly assumed that as manufacturing numbers increase, precision would inherently suffer. I would still love to build my own engine someday just...
  14. Built Motor, Stock Tune, Longer Life?

    Engine Modifications
    My 2013 WRX came with a standard 36,000 mile powertrain warranty. Hennessy's 600 HP F-150 Velociraptor has a 36,000 mile powertrain warranty..... I think its safe to say that the OEMs aren't the end all/be all in terms of build quality/performance. Keep in mind that the non-luxury OEMs are...
  15. Built Motor, Stock Tune, Longer Life?

    Engine Modifications
    Fair enough.
  16. Built Motor, Stock Tune, Longer Life?

    Engine Modifications
    So even though the OEM pistons have been known to have ring land failures, they are still the preferred choice when keeping the engine in stock form?
  17. Built Motor, Stock Tune, Longer Life?

    Engine Modifications
    Makes sense, thanks.
  18. Built Motor, Stock Tune, Longer Life?

    Engine Modifications
    I get that built motors typically don't last nearly as long as OEM strictly from a mileage point of view, but isn't that mostly due to tuning the engine to achieve HP numbers it was never designed for?
  19. Built Motor, Stock Tune, Longer Life?

    Engine Modifications
    Couldn't you say that has more to do with the aggressive tuning and horsepower increase that typically comes with 'built' engines?
  20. Built Motor, Stock Tune, Longer Life?

    Engine Modifications
    IN THEORY, if I built a EJ255 motor with forged rods/pistons/Manley crank, King bearings etc. (doesn't have to be those parts exactly, just an example) and kept heads, compression, boost, turbo, injectors, intake, exhaust and tune STOCK....what would that do to the life of the motor if anything...
